-15x+10+15=3x+7-2\left(4x-1\right)
Use the distributive property to multiply 5 by -3x+2.
-15x+25=3x+7-2\left(4x-1\right)
Add 10 and 15 to get 25.
-15x+25=3x+7-8x+2
Use the distributive property to multiply -2 by 4x-1.
-15x+25=-5x+7+2
Combine 3x and -8x to get -5x.
-15x+25=-5x+9
Add 7 and 2 to get 9.
-15x+25+5x=9
Add 5x to both sides.
-10x+25=9
Combine -15x and 5x to get -10x.
-10x=9-25
Subtract 25 from both sides.
-10x=-16
Subtract 25 from 9 to get -16.
x=\frac{-16}{-10}
Divide both sides by -10.
x=\frac{8}{5}
Reduce the fraction \frac{-16}{-10} to lowest terms by extracting and canceling out -2.
